Our assessment
The evidence shows that this product contains calcium, a mineral essential for bone health and nerve function. For most adults, achieving the recommended intake through diet is ideal, but supplementation can fill gaps. However, our assessment is that you should approach calcium supplements with caution due to potential risks at high doses [NIH ODS].
How it works
Think of calcium as a builder and messenger in your body. It supports bone mineralization and density, and it helps your muscles relax and your nerves signal properly. This dual role makes it critical for overall structural and functional health [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports for this product category. For calcium specifically, side effects reported include constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, and abnormal heart rhythms at very high levels. High calcium intake might also increase the risk of heart disease and prostate cancer. Data not available on specific report counts for each calcium side effect [FDA data] [NIH ODS].
Our recommendation
Start by assessing your dietary calcium intake before supplementing. If you choose to use this product, take it with food to improve absorption and be aware that it can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin. Do not exceed the recommended dose on the label [NIH ODS].
